Advantages:
1. High material utilization
2. Good quality
3. Good working conditions, high productivity
4. Low production costs

Ring rolling machine are divided into the radial rolling and radial-axial rolling(D53K series,CNC controlled). The radial rolling are divided into vertical type (D51 series) and horizontal type (D52 series, PLC controlled).
